**Question-1.**Let A & B are two sample of ideal gases of equal mole .let T be the temperature of both the gas Let E_{A} and E_{B} are there total energy respectively .Let M_{A} and M_{B} are these respective molecular mass .which of these is true

a,E_{A} > E_{B}

b,E_{A} < E_{B}

c,E_{A} =E_{B}

d,none of these

**Solution:1**

E_{A} = 3/2 nRT

E_{B} = 3/2 nRT

;E_{A} =E_{B}

a,11v

b,v(11)

c, v

d, 3.3v

Vrms= (∑ V

= [(V

=v(11)

An ideal gas A is there.Intial temperature is 27°C.The temperature of the gas is increased to 927°C.Find the ratio of final V

V

So it is proportional to Temperature

Now

T

T

So intial V

Final V

ratio of final to intial=2:1

Given that on absolute scale

Triple point of water on scale A = 200 A

Triple point of water on scale B = 350 B

Also, triple point of water on Kelvin scale = 273.16 K

Now temperature on scale A and on scale B is equivalent to 273.16 K on absolute temperature scale.

Thus, value of one degree on absolute scale A = (273.16/200) K

Or,

Value of temperature T

Similarly value of temperature T

Since T

273.16×T

Or, T

a.the molecules of the gas are in continual random motion

b. The molecules interact during the collison

c. The molecules are tiny hard sphere undergoing inelastic collision

d. The collison are of short duration

Answer is c

There are two statement

A. Equal volumes of all gases at the same temperature T and pressure P contain an equal no of Molecules

which one of the following is correct

a. A and B both

b. A only

c B only

d. A and B both are incorrect

Answer is b

A. The V

B. The V

which one of the following is correct

a. A and B both

b. A only

c B only

d. A and B both are incorrect

Answer is b

a. The pressure of the gas is equal to the total kinetic energy of the molecules in a unit volume of the gas

b. The product of pressure and volume of the gas is always constant

c. The average kinetic energy of molecule of the gas is proportional to its absolute temperature

d. The average kinetic energy of molecule of the gas is proportional to the square root of its absolute temperature

Answer is c

a. The attractive forces between the molecules is not negligible

b Volume of the molecules is negligible as compared to the volume occupied by the gas

c. Volume of the molecules is not negligible as compared to the volume occupied by the gas

d. The attractive forces between the molecules is negligible

Answer is a,c
